Optima Blue DC 4.2 12v 55Ah

The OPTIMA BLUETOP battery gives you power you can rely on. Its patented SPIRALCELL TECHNOLOGY means faster runtime, faster charging and up to twice the life of traditional marine batteries. It is purpose-built to meet the demanding challenges of marine applications. The OPTIMA BLUETOP battery is completely leak-proof and maintenance-free. It is very light and can be mounted virtually anywhere and in any position. It is over 15 times more vibration-resistant than other batteries, which matters in the boat hull. And it holds its charge longer and recharges faster thanks to its remarkably low self-discharge rate. That can mean a faster return to the water after the off-season. They can be used in all starting and deep discharge applications (marine accessories, house applications, trolling motors, bow thrusters). Benefits: Lasts up to three times longer than other batteries. More power during the initial and subsequent two, five and 10 seconds of starting torque than equivalent standard lead-acid batteries. Consistent performance quality that allows your battery to deliver the same power even when discharged. Ideal for seasonal use. A fully charged battery can last 12 months at room temperature (or lower) and still provide the power needed to start your boat's vehicle. Fifteen times better vibration resistance than other batteries. Leak-proof and completely flexible; it can be mounted in almost any position.
